What is business cash management at Western Alliance Bank?

Western Alliance Bank business cash management is the set of tools and services that consolidate balances across corporate accounts, automate sub-account funding, optimize idle cash, and forecast future liquidity. Treasurers configure zero-balance accounts, sweep structures, and concentration arrangements; the bank runs the automated cash movements end-of-day; the CFO sees consolidated liquidity and future projections from one dashboard.

How does a zero-balance account work?

A zero-balance account (ZBA) is a subsidiary or payroll account that settles every business day to zero. Debits clear normally during the day; at end of day, the master concentration account funds the net debit position to bring the ZBA back to zero. Credits sweep up to the master. ZBA structures eliminate idle balances in sub-accounts, centralize liquidity at the master, and give controllers real-time insight into sub-unit activity without scattered balances.

Which customers benefit most from cash management?

Cash management delivers the most value to companies operating multiple accounts — subsidiaries, franchise units, separate payroll entities, investor property LLCs, multiple store locations. Single-account businesses benefit primarily from the sweep feature to avoid idle cash. Multi-entity customers benefit from ZBA consolidation, concentration reporting, and forecasting across the entire corporate footprint.

Liquidity forecasting projects future cash positions using historical patterns and scheduled payments. Positive pay protects outgoing check and ACH activity from fraud before it posts.

Western Alliance Bank ZBA and concentration workflow with subsidiary accounts funding master account end of day

End-of-Day ZBA Sweep

During the business day, sub-accounts (subsidiary operating, franchise unit, payroll, investor property LLC) receive debits and credits normally. At end of day, the bank calculates the net position of each sub-account. Sub-accounts with net credits sweep up to the master concentration account. Sub-accounts with net debits receive funding from the master to bring them to zero. The master carries the consolidated net balance of the entire structure.

The next business morning, the portal shows each sub-account at zero with the day's activity reported. The master shows the consolidated balance plus a transaction-level drill-down across every sub-account. Reporting aggregates by entity, region, line of business, or any custom hierarchy — configured once in the business portal and reflected in every report thereafter.

Investment Sweep

Use when excess cash sits idle in the operating account and the business is not drawing on a revolving line of credit. Idle balances above a target threshold sweep into money market funds or overnight treasury investments. Yield varies with short-term rates set by Federal Reserve policy. Principal is not FDIC insured — these are investments, not deposits — but typically carry very low risk. Morning return brings funds back to the operating account as needed.

Loan Sweep

Use when the business carries balances on a revolving line of credit and pays interest on that balance. Idle operating cash automatically pays down the LOC instead of sitting at a low deposit yield. Interest on the revolver is almost always higher than earnings credit on the deposit — a loan sweep is usually the better economic choice if both facilities exist. The sweep re-draws on the LOC as needed to cover the next day's debits. Cross-reference lines of credit for structure detail.

Historical Pattern Learning

The model ingests the last 12-24 months of account activity, identifies recurring payment patterns (payroll, rent, vendor invoices), and learns day-of-week and day-of-month seasonality. No manual tagging required.

Scheduled Payments Input

Outstanding ACH batches, pending wires, recurring bill pay, and tax payments layer onto the historical base. Scheduled items appear on their execution date in the forecast chart.

Scenario Toggles

Toggle scenarios: delayed customer receipt, large vendor prepayment, LOC draw. The forecast recalculates and highlights tight liquidity days. CFOs use the result for working capital decisions.
